Abstract

The utility model discloses pin hole slack adjusters, including doorframe, door-plate and bolt, the door-plate is hinged on the doorframe, the bolt is arranged in the door-plate, pin hole is provided on the doorframe, flange is provided on the pin hole, the plane of the flange and the doorframe has certain angle, angle is between 115 ° to 125 °, when the bolt is inserted in the pin hole, the flange is generated deformation by the active force of the bolt, the flange is promoted to stand tightly against the two sides that bolt is stated in residence, to fix the bolt, prevent door-plate from generating shaking, it can also be by adjusting the case where angle of the flange causes bolt that cannot lock come deviation caused by the enabling of when preventing production and improper pass.The utility model is easy to use compared with traditional structure operation, it is simple and reasonable, be easily worked, greatly improve the serious forgiveness of production, improve production efficiency.

Description

Pin hole slack adjuster

Technical field

The utility model relates to safety door technical fields, fill more particularly, to the pin hole gap adjustment on a kind of safety door It sets.

Background technique

Currently, the security door of security door producer production, the either structures such as simple gate or clamshell doors, big and small door, upper underthrust Lower gear uses substantially on the corresponding doorframe of pin rushes single kidney slot mode, and the stainless of a drawing and forming is then buckled into hole Steel dust cover or plastic jacket.

This structure exists as following drawbacks: first is that the kidney slot that lower gear rushes on doorframe is greatly by about one time than upper and lower lock plug, leading Cause is shut behind the door, and door-plate upper and lower ends can shake under external force；Second is that being deposited in doorframe and door-plate process in production In dimensional discrepancy, easy deviation cannot lock, and assemble the lockhole that will polish at this time；Third is that being used after user installation Middle door-plate abnormal condition lower switch is not capable of resetting since accidental impact causes to lock to insert to deform, and user cannot oneself adjustment.

For this purpose, many manufacturers and knowledgeable people develop and manufacture experimently regarding to the issue above, but there has been no more so far It emerges for reasonable product.

Summary of the invention

In view of the deficiencies of the prior art, the utility model provides pin hole slack adjuster, can limit bolt, The case where guaranteeing that door-plate will not shake, dimensional discrepancy when production can be prevented and cause bolt that cannot lock, easy for operation, It is simple and reasonable, be easily worked, greatly improve the serious forgiveness of production, improve production efficiency.

The technical scheme adopted by the utility model to solve the technical problem is as follows: pin hole slack adjuster, including door Frame, door-plate and bolt, the door-plate are hinged on the doorframe, and the bolt is arranged in the door-plate, are set on the doorframe It is equipped with pin hole, flange is provided on the pin hole, the plane of the flange and the doorframe has certain angle, angle Between 115 ° to 125 °, when the bolt is inserted in the pin hole, the flange is produced by the active force of the bolt Raw deformation, promotes the flange to stand tightly against the two sides that bolt is stated in residence, to fix the bolt, prevents door-plate from generating shaking.

Another side direction of the bolt is arranged in the further scheme of the utility model, the flange.

The angle of the further scheme of the utility model, the flange can be adjusted by tool.In this way, It can prevent dimensional discrepancy when production and bolt is prevented to be also possible to prevent wrongful enabling from situation about being inserted on pin hole and close Deviation that door generates and the case where bolt cannot be made to be locked.

The further scheme of the utility model, the pin hole have 2, are separately positioned on the top and bottom of the doorframe Portion.In this way, the fixation of end of door plate is more firm, it is ensured that door-plate does not generate shaking.

The further scheme of the utility model, the door-plate include cervical orifice of uterus and female door, the cervical orifice of uterus and the mother Men Caiyong Split mode, the bolt are arranged on the cervical orifice of uterus.It goes away in this way, usually opening the door to close the door, it is not necessary to push too big Yishanmen；Or the half in bivalve door is too small inconvenient current.When needing through big objects such as furniture, can all beat It opens.Different closed states can be selected according to the actual situation.

The beneficial effects of the utility model are: first is that be provided with flange on the pin hole, the flange and the doorframe Plane have certain angle, angle be 115 ° to 125 ° between, it is described to turn over when the bolt is inserted in the pin hole While the active force by the bolt generates deformation, the flange is promoted to stand tightly against the two sides that bolt is stated in residence, to fix Bolt is stated, prevents door-plate from generating shaking.Second is that being produced when closing the door in production process there are the deviation of some sizes and improper enabling When raw deviation, the bolt can be matched by adjusting the angle of the flange, prevent bolt from shaking.The utility model compared with Traditional structure operation is easy to use, it is simple and reasonable, be easily worked, greatly improve the serious forgiveness of production, improve life Produce efficiency.

Specific embodiment

Show as shown in Figure 1 to Figure 4, pin hole slack adjuster, including doorframe 1, door-plate 2 and bolt 3, the door-plate 2 is hinged On the doorframe 1, the door-plate 2 includes cervical orifice of uterus 21 and female door 22, and the cervical orifice of uterus 21 and female door 22 use split shape Formula, the bolt 3 are arranged in the cervical orifice of uterus 21, pin hole 4 are provided on the doorframe 1, is provided with and turns on the pin hole 4 Another side direction of the bolt 3 is arranged in side 5, the flange 5, and the plane of the flange 5 and the doorframe 1 has centainly Angle, angle are set as between 115 ° to 125 °, and after closing cervical orifice of uterus 21, the bolt 3 is pushed up, makes the bolt 3 When being inserted in the pin hole 4, the flange 5 is generated deformation by the active force of the bolt 3, promotes the flange 5 tightly The two sides of the bolt 3 are abutted against, to fix the bolt 3, prevent door-plate 2 from generating shaking.

Bolt is also possible to prevent improper from situation about being inserted on pin hole for dimensional discrepancy when solving production Enabling close the door the deviation generated and the case where bolt cannot be made to be locked.The angle of the flange 5 can by tool come It is adjusted.

In order to keep the fixation of door-plate 2 more firm, guarantee that door-plate 2 does not generate shaking, there are two the pin holes 4, respectively The top and bottom of the doorframe 1 are set.
